Answer 1

(a)-2-8= -10

(b) +8 + 9 = 17

(c) - 10 + 50 = 40

(d)50 - 60 = -10

(e) + 40 – 30 = 10

(f) - 20 - 30 = -50

(g) +2-8= -6

(h) -8 + 9 = 1

(i) - 10 - 50 = -60  

(j) - 50 - 60 = -110

(k) - 40 - 30 = -70

(l) - 20 + 30 = 10

(m) + 12 - 8 = 4

(n) -8 +10 = 2

(0) - 30 - 50 = -80

(p) 50 - 70 = -20

(q) - 40 + 30 = 10

(r) +20 + 30 =​
